Having a one-night stand can lead to consequences such as unwanted or unplanned pregnancies, sexually transmitted diseases, depression, stress, and other less-than-ideal circumstances. Emotional distress following a one-night stand is more commonly reported among women.
When having unprotected sex, pregnancy is a realistic possibility. Becoming pregnant as a result of a one-night stand increases the chances of an unwanted pregnancies, largely due to the fact that both parties are not in a committed relationship with each other. The decision on whether or not to keep the child becomes a more difficult one, as parents often consider the quality of life that the child could have if both parents aren't committed to parenting.
Sexually transmitted diseases are a risk of having a one-night stand if parties have unprotected sex. Some STDs include HIV/AIDS, syphilis, gonorrhea, herpes and chlamydia. There is often no way to tell if a person is infected with an STD from looks alone. While some STDs may be treated with antibiotics, others are caused by viruses. Those infected with viruses can maintain the infection with medication but not cure it.
Even if a person has protected sex during a one-night stand, other emotional issues can result. Some people report feelings of feeling used and degraded afterwards, particularly women.
